(19,-9) (-7,-15) in slope intercept form

Mathematics

never [62]2 years ago

8 0

Answer:

$y=\frac{3}{13}x-\frac{174}{13}$

Step-by-step explanation:

slope:

$m=\frac{-15-(-9)}{-7-19} =\frac{-15+9}{-26} =\frac{-6}{-26} =\frac{3}{13}$

Equation, with the point (19, -9):

$y-(-9)=\frac{3}{13} (x-19)$

$y+9=\frac{3}{13} x-\frac{57}{13}$

$y=\frac{3}{13} x-\frac{57}{13} -9$

$-9=-9(\frac{13}{13} )=-\frac{117}{13}$

$y=\frac{3}{13}x-\frac{174}{13}$

P(x) = x4 − 9x2 − 4x 12? what some roots

arlik [135]

P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2

In triangle ABC, angle = 90 degrees. AC = 7, BC = 12. AB = _______ Measure of angle A = _______ Measure of angle B = _______

Ulleksa [173]

Answer:

AB = 13.89

Measure of angle A = 59.74°

Measure of angle B = 30.26°

Step-by-step explanation:

The given parameters are;

∠C = 90°

AC = 7

BC = 12

Part 1

Hence, the question has the dimensions of the two adjacent sides of the right angle (angle 90°)

From Pythagoras theorem, we have;

A² = B² + C²

Where, A is the opposite side to the right angle, hence;

In the ΔABC,

AB ≡ A

Therefore;

AB² = AC² + BC² = 7² + 12² = 193

∴ AB = √193 = 13.89

Part 2

∠A is the side opposite side BC such that by trigonometric ratios

$tan \angle A = \frac{Opposite \, side \, to \, angle \, A}{Adjacent \, side \, to \, angle \, A} = \frac{BC}{AC} = \frac{12}{7} = 1.714$

∴ ∠A = Arctan(1.714) or tan⁻¹(1.714) = 59.74°

Part 3

∠B is found from knowing that the sum of the angles in a triangle = 180°

∴ ∠A + ∠B + ∠C = 180° which gives

59.74° + 90° + ∠B = 180°

Hence, ∠B = 180° - (59.74° + 90°) = 180° - 149.74° = 30.26°.

When rounded to the thousands place, which of the numbers below round to 89,000? Select all that apply. A) 89,458 B) 88,450 C) 9

slega [8]

Answer:

A) 89,458 and

E) 88,615

When rounded to the thousands place, the numbers above will round to 89,000

Step-by-step explanation:

A) 89,458

When rounded to the thousands place, the number above will round to 89,000 because 458 is less than 500 .

In rounding we check the number next to the number which is to be rounded.

If that number is less than 5 it is dropped off and if it is greater and equal to 5 it is added to the next number.

In this number we check the hundreds place to round to the thousands number.

B) 88,450

When rounded to the thousands place, the number above will round to 88,000 because 450 is less than 500 .

C) 90,054

When rounded to the thousands place, the number above will round to 90,000 because 0 is less than 5 at the hundreds place .

D) 89,905

When rounded to the thousands place, the number above will round to 90,000 because 905 is greater than 500 .

E) 88,615

When rounded to the thousands place, the number above will round to 89,000 because 615 is greater than 500 .
